I've been using bitcoin since 2014 and i will say that bitcon is more profitable than earning from descent job from office where you can get money bitcoin there are chance that bitcoin can be grow when you are stocking them into your wallet money is you just ready to spend them or put into bank with 1% interest of it in bitcoin you can do activities like trading , gambling , and investmenst.
There are many differences. I agree the bitcoin is much more profitable than fiat. Bitcoin is virtual, fiat is physical, decentralization/centralization, anyone can have a bitcoin wallet, only adults can have accounts at the banks, and consequently, only adults can deal with money on the internet with fiat payment system sites. Bitcoin makes the world easier to buy, sell and hire services.
